## API Usage Examples

For direct API access, all scripts use curl under the hood:

```bash
# Direct TTS API call
curl -X POST "https://api.elevenlabs.io/v1/text-to-speech/VOICE_ID" \
  -H "xi-api-key: $ELEVENLABS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hello world", "model_id": "eleven_turbo_v2_5"}' \
  --output speech.mp3
```

## Error Handling

All scripts provide helpful error messages:

- **401**: Authentication failed - Check your API key
- **403**: Permission denied - Your API key may not have access
- **429**: Rate limit exceeded - Wait before trying again
- **500/502/503**: ElevenLabs API issues - Try again later

## Testing

Run the test suite to verify everything works:

```bash
{baseDir}/test.sh YOUR_API_KEY
```

Or with environment variable:
```bash
export ELEVENLABS_API_KEY="your_key"
{baseDir}/test.sh
```

## Troubleshooting

### Common Issues

1. **"exec host not allowed (requested gateway)"**
   - The skill needs to run commands in a sandbox environment
   - Configure OpenClaw to use sandbox: `tools.exec.host: "sandbox"`
   - Or enable sandboxing in your OpenClaw config
   - Alternative: Configure exec approvals for gateway host (see OpenClaw docs)

2. **Parse errors with quotes or exclamation marks**
   - Use single quotes instead of double quotes: `'Hello world'` not `"Hello world!"`
   - Avoid exclamation marks (`!`) in text when using double quotes
   - For complex text, use the `--input` option with a file

3. **"ELEVENLABS_API_KEY not set"**
   - Ensure `ELEVENLABS_API_KEY` is set or configured in openclaw.json
   - Check that the API key is at least 20 characters long

2. **"jq is required but not installed"**
   - Install jq: `apt-get install jq` (Linux) or `brew install jq` (macOS)

3. **"Rate limited"**
   - Check your ElevenLabs plan quota at elevenlabs.io/app/usage
   - Free tier: ~10,000 characters/month

4. **"Voice not found"**
   - Use `{baseDir}/scripts/voices.sh list` to see available voices
   - Check if the voice ID is correct

5. **"Dubbing failed"**
   - Ensure source audio is clear and audible
   - Check supported language codes

6. **"File too large"**
   - Transcription: 100MB max
   - Dubbing: 500MB max
   - Voice cloning: 50MB per file

### Debug Mode
```bash
# Enable verbose output
DEBUG=1 {baseDir}/scripts/speak.sh 'test'

# Show API request details
DEBUG=1 {baseDir}/scripts/transcribe.sh audio.mp3
```
